Page 2 Name Description/Characteristics/Notes Drosophila melanogaster, Wild type (+) Normal characteristics (red eyes and normal wing size). Drosophila mojavensis Long life cycle (approximately one month).Useful for comparative population studies and for preparing salivary gland chromosome squashes. Drosophila virilis One of the largest Drosophila species. Useful for preparing salivary gland chromosome squashes. Chromosome I Mutants (Sex-Linked) Apricot (a) Apricot eyes, males' eyes slightly larger than females'. Bar (B) Bar eyes (narrow vertical bar), males' eyes larger than females'. Forked (f ) Forked bristles. Miniature (m) Miniature wings (slightly longer than abdomen, but with normal proportions); dark gray and less transparent than normal. Ruby (b) Clear ruby eyes. Vermilion (v) Vermilion (bright red) eyes. White (w) White eyes. White-Crossveinless-Forked (w; cv; f ) White eyes, crossveinless wings, forked bristles. White-Miniature-Forked (w; m; f ) White eyes, miniature wings, forked bristles. Yellow (y) Lightest body color. Yellow-Forked-Attached, and White (yf:=&w[1]) Females: normal eyes, yellow body with forked bristles, normal wings. Males: white eyes, gray body, normal wings. Note: Remove culture from stock when all females have died or when all flies have white eyes. Yellow-White (y;w) Lightest body color, white eyes. Yellow-White-Miniature (y;w; m) Lightest body color, white eyes, miniature wings. Chromosome II Mutants Apterous (ap) Wingless (lacking all wing blade structures). Black (b) Black body (darker at cooler temperatures). Black-Purple-Curved (b;pr;c) Black body, purple eyes (ruby upon emergence, darken to purple with age), curved wings. Black-Vestigial (b;vg) Black body, vestigial wings. Brown (bw) Brown eyes (light brown/wine upon emergence, darken to garnet with age). Produces white eyes when crossed with vermilion, cinnabar, or scarlet. Cinnabar (cn) Cinnabar eyes (slightly brighter than wild, dull with age). Dumpy (dp) Truncated wings (approximately half normal length). Heldout (ho) Wings extended at right angles to body. Lobe (L) Lobe-shaped eyes (slightly reduced size with a nick in anterior edge; lower half reduced more than upper half ). Star-Curly (S;Cy) Eyes rough, slight smaller and narrower than wild type. Wings curved upward. Vestigial (vg) Vestigial wings (increase in size at 29°C or higher). Vestigial-Brown (vg;bw) Vestigial wings, brown eyes (darken with age). Chromosome III Mutants Antennapedia (Antp) Legs grow in place of antennae. Ebony (e) Shiny black body. Scarlet (st) Scarlet (eyes bright vermilion; darken with age). Sepia (se) Sepia eyes (brown at emergence, darken to sepia, become black with age). Sepia-Ebony (se;e) Sepia eyes, shiny black body. Chromosome IV Mutants Eyeless (ey) Eyes half to one-quarter normal size. Polished (pol) Eyes without facets (glasslike). Multichromosomal Mutants Curly/Plum (II); Dichaete/ Stubble (III)(Cy/Pm;D/sb) Curly wings, plum eyes, wings divergent, bristles short and thick. Easily prone to contamination; subculture frequently. Dumpy (II); Sepia (III)(dp;se) Truncated wings, sepia eyes. Vestigial (II); Sepia (III)(vg;se) Vestigial wings, sepia eyes. Vestigial (II); Ebony (III)(vg;e) Vestigial wings, shiny black body. Yellow-Forked-Attached, and White (I); Apterous (II)(yf:=&w[1];ap[2]) Females: normal eyes, yellow body, apterous wings. Males: white eyes, gray body, apterous wings. Note: Remove culture from stock when all females have died or when all flies have white eyes.
